Question

What caused the different pH values for the test solutions? Each solution has a different concentration of ions. hydroxide or hydrogen?

Answer 1

Answer:

Hydrogen

Explanation:

By definition a difference in pH is a difference in amount of hydrogen ions

Answer 2

Answer: The correct answer is hydrogen.

Explanation:

pH is defined as the negative logarithm of hydrogen or hydronium ion concentration that are present in a solution.

The equation representing pH of the solution follows:

$pH=-\log[H^+]$

pH range of the solution varies from 0 to 14.

If the pH of the solution is from 0 to 6.9, the solution is said to be acidic.

If the pH of the solution is from 7.1 to 14, the solution is said to be basic.

If the pH of the solution is 7, the solution is said to be neutral.

Thus, different concentration of hydrogen ions will give us different values of pH.

Hence, the correct answer is hydrogen.
